This study describes and explains the revolutionary changes which
transformed the agricultural life of the Islamicized world in the four
centuries following the early Arab conquests. Professor Watson discusses
eighteen crops - from sorghum and rye to the watermelon - which spread
through the Near East and North Africa during this period. Their
origins, diffusion and uses are reviewed. The book investigates the
mechanics of diffusion, the routes by which plants spread, and the
processes by which they were acclimatized in their new environment. The
social and economic history of agriculture in the medieval Islamic world
is assessed in a review of wide importance. Professor Watson sets out to
refute the view that the early Islamic period was one of agricultural
decline in the Near East. He shows that, in contrast to the late Roman
and Sasanian periods, it was a time of agricultural and demographic
expansion. Agricultural innovation in the early Islamic world will be of
interest to economic, social and agricultural historians and to those
concerned with Islam and its effect on Africa and Asia.
